Initial 3D Mark Score


Initially, the TITAN 3-way SLI configuration scored a 3DMark 11 result of P25177. That's 9,495 points higher than the former CrossFireX setup's score (P15682).

I will be performing another round of 3D benchmarks soon comparing PCI-E GEN2 (this initial score) with performance after enabling PCI-E GEN3 bus speed.

Score P25177
  • Graphics: 38241
  • Physics: 13382
  • Combined: 11125
  • Graphics Test 1 167.4 FPS
  • Graphics Test 2 198.9 FPS
  • Graphics Test 3 252.9 FPS
  • Graphics Test 4 111.2 FPS

I use BONIC to crunch the SETI@Home project. The system receives 48,000 credits per day on average crunching at 100%:


Here's an interesting observation: Each TITAN crunches 1% of a cuda-fermi work unit every second, so three work units are finished off every minute-and-a-half. When it comes to crunching a work unit, a single TITAN Kepler GPU is about fifteen-times faster than a single 3960X thread. However, the 3960X has 12 threads munching on 12 work units at the same time...

Warning: Spoiler! (Click to show)
All three GTX TITAN cards are operating well together in SLI.

Thankfully, the migration away from CrossFireX to 3-Way SLI went smoothly. After uninstalling the AMD Catalyst driver and shutting down, the former XFX Double D Black Edition Radeon 7970 cards were removed.

The only complicating factor when installing the three TITAN cards was providing a third PCIE power cable with 6 and 8-pin connectors from the Enermax PSU. The MSI Big Bang XPower II mainborad and Cosmos II case are both very large, offering excellent clearance between components. Air flow is also good, especially in the GPU area. There is plenty of room to work inside the case and it does not look overly crowded even after installing all three TITAN cards.

I am hoping this configuration will provide good thermal performance. Benchmarks will be taken next after the initial NVIDIA driver setup and EVGA Precision configuration process is completed...






























Titanic installation indeed. Very nice!

EVGA Precision Overclock Metrics


After several hours of testing, I eventually settled on the following overclock configuration for all three TITAN cards using EVGA Precision 4.1.0, providing a very stable average overclock of 269MHz across all three TITAN video cards while gaming or folding under heavy load:







Note how the bottom card operates about 10C cooler under heavy load compared with the other two cards. For comparative purposes, a stock TITAN from EVGA clocks at 837MHz with a boost of 876MHz:


EVGA Stock TITAN

  • Base Clock: 837MHz
  • Boost Clock: 876MHz


The installed SuperClocked edition TITAN cards from EVGA clock higher by 39/52MHz respectively:

EVGA SuperClocked TITAN

  • Base Clock: 876MHz (39MHz > Stock)
  • Boost Clock: 928MHz (52MHz > Stock)


Under heavy gaming and 100% folding load the highest sustained and stable clock rate was 1123MHz, which is 286MHz above stock. The overall average improvement across all three TITAN cards was 269MHz.

EVGA SuperCLocked TITAN - LOAD

  • TITAN-1: 1084MHz (247MHz > Stock)
  • TITAN-2: 1123MHz (286MHz > Stock)
  • TITAN-3: 1110MHz (273MHz > Stock)
  • TITAN-AVERAGE: 1106MHz (269MHz > Stock)


Below is a gaming screen shot with Precision OSD metrics while playing BF3 with 63 other online players at 2560 x 1600 using ultra rendering quality:



I haven't seen FPS drop below 100 yet, and if I'm a good boy the rest of this year . . . perhaps Santa will bring a few more display panels to fully complete this build!

Enabling PCI-E GEN3 Bus Lanes Improves 3D Mark Score


The 3DMark 11 score increased to 25,921 after enabling PCI-E GEN3 bus speed. The MSI Big Bang XPower II default is PCI-E GEN2. That's a 3% gain, which is not a big increase but significant enough. I will take any increase that helps insure a fast and smooth frame rate.

Based on my research, enabling PCI-E GEN3 delivers a much more noticeable improvement in multi-panel surround setups. The extra GEN3 bus bandwidth kicks in when display resolutions cross into worlds rendered at 5760 x 1200 and higher...

I hope with 3000$ worth of card power your fps does not dip below 100 -_-

Regarding the PCI-E GEN3 benchmark, I must not be generating enough load on the bus while running the standard 3DMark 11 benchmark to see more than a 3% boost.

I will probably have to wait until I move from a single panel to a multi-panel configuration. Perhaps going to 4-way SLI would also take more advantage of PCI-E GEN3 bandwidth. Both would multiply bus traffic to considerably higher busy levels...
